HP Notebook PCs - Resolving Coprocessor Error Message

Some computers are designed to use a dual core processor or a coprocessor to improve performance. A coprocessor is an additional chip designed to supplement the central processing unit (CPU) of the computer. Essentially, coprocessors give added speed and efficiency in the way the computer handles information.

On some occasions, non-standard video drivers loaded onto a computer can cause conflicts with the coprocessor, resulting in an error message. One visual indication of a problem with a corrupted driver, or a conflict between the BIOS and a driver, is the display of a yellow exclamation point next to a driver in Device Manager window. These conflicts can occur if you:

Install a retail copy of Windows Vista.

HP does not recommend installing a retail copy of Windows Vista on computers that were either designed for Windows XP, or may not meet the advanced hardware capabilities of more powerful versions of Windows Vista.

Install a non-HP video driver.

HP does not recommend downloading and installing drivers that are not tested and validated by HP. Installing non-supported drivers could cause unwanted problems such as intermittent, unexpected rebooting or crashing of the operating system.

Right click on the device shown under Other Devices and select Update Driver.

On the Hardware Update Wizard, select No, not this time and then click Next.

Select Install from a list or specific location (Advanced) and then click Next.

Select Include this location in the search and then click Browse.

Navigate to C:\swsetup\sp33031 and click the SP33031 folder.

Click OK, click Next, and then follow the on-screen instructions.

note:

The default location for the required drive is C:\swsetup\sp33031. The file is smuc.inf. If the file is not in this folder, download and install a driver update (SP33031 or later). You may do so by going to the HP Drivers and Downloads site.

The best way to resolve a coprocessor error message caused by a missing or invalid video driver is to install the valid HP drivers for the specific computer model. Use one of the following methods.

Go to the HP Drivers and Downloads web site, search for drivers for the specific computer model, and then select the video driver to download it. Follow the instructions included with the updated file to install the driver correctly.

Use HP Health Check to test the system and download the required drivers.

Click Start and type Health in the search menu. Then select HP Health Check when it becomes available.

Follow the on-screen directions to obtain the latest version of the video driver and any other updates that might be recommended at this time.

Obtaining and installing HP-tested video drivers should resolve the coprocessor error messages and prevent them from reoccurring.
